[SCSI] mpt fusion: Code Cleanup patch

Browse source 
Resending patch considering Grants G's code review.

Main goal to submit this patch is code cleaup.
1. Better driver debug prints and code indentation.
2. fault_reset_work_lock is not used anywhere. driver is using taskmgmt_lock
instead of fault_reset_work_lock.
3. setting pci_set_drvdata properly.
4. Ingore config request when IOC is in reset state.( ioc_reset_in_progress
is set).
5. Init/clear managment frame proprely.(INITIALIZE_MGMT_STATUS and
CLEAR_MGMT_STATUS)
